For an executive with a reputation for making bold moves, Dombrowski may have made his boldest one yet Tueday by shipping arguably the organization's best position player prospect (Yoan Moncada) and its best pitching prospect (Michael Kopech), along with two others, to the Chicago White Sox for lefty ace Chris Sale.

Adding Sale to a rotation that already includes reigning Cy Young Award winner Rick Porcello and David Price gives the Red Sox the American League's best rotation and makes the Sox the team to beat in the A.L.

Hired 17 months ago with a mandate to make the Red Sox winners again after three last-place finishes in the span of four seasons, Dombrowski has acted aggressively and decisively.

Since then, he's obtained Price, Craig Kimbrel, Carson Smith, Drew Pomeranz, Tyler Thornburg and Sale. That translates into three lefty starters and three back-end power arms in the bullpen.

Of course, all those moves have come at a significant cost. Dombrowski has gone through the Red Sox' minor-league system and shredded it, sacrificing Anderson Espinoza, Manuel Margot, Javier Guerra, and now, Moncada and Kopech.

The pitching, in particular, has been stripped bare, with Espinoza and Kopech representing the two best arms in the system. And in Moncada, the Sox gave up on arguably the single most talented propsect in the entire sport.

At a time when teams protect their best young players as though their existence depends on them, Dombrowski has demonstrated a willingess to move them for a chance to win now.

In exchange, the Sox have now built a super rotation, with three front-line starters, augmented by two other lefties (Pomeranz and Eduardo Rodriguez) along with Steven Wright and Clay Buchholz.

It's a virtual certainty that the Sox will move one of those arms now, in a market where there's virtually no quality free-agent starters available.

Buchholz, who stands to earn $13.5 million in 2017, would give them payroll relief, while Rodriguez, because of his youth and upside, might give the team its biggest return.

Dombrowski's moves create a window for the Red Sox. Sale's deal runs through 2019, while Price has an opt-out in his deal after 2018.

That creates some urgency for the Red Sox to capitalize on the strength of their rotation and a nucleus of young position players -- Mookie Betts, Xander Bogaerts, Jackie Bradley Jr., Andrew Benintendi -- and win multiple titles in the next few seasons.

Red Sox CEO Sam Kennedy on Monday confirmed the Sox are interested to play the Yankees in London during next year's regular season. Bloomberg reported the clubs are nearing an agreement to play two games there in June 2019. Discussions are indeed taking place, but a deal is not done.

Red Sox signal they'll keep Swihart, may trade Marrero or Holt

Red Sox signal they'll keep Swihart, may trade Marrero or Holt

Blake Swihart’s strong spring seems to have the Red Sox more inclined to deal one of their natural utility infielders, such as Brock Holt or Deven Marrero, rather than Swihart, a converted catcher with high upside who's getting a look in other roles.

"We do have depth with our middle infielders," Sox president of baseball operations Dave Dombrowski said Monday. "However, [I] would not get into potential trade discussions."

Swihart, who turns 26 on April 3, is most valuable as a catcher. But he could still be useful in a bench role for the 2018 Red Sox, and a win-now mentality may be the driving force here. (It is possible, as well, that there is nothing available via trade for Swihart that has piqued the Sox’ interest. Marrero or Holt wouldn’t require as much in return.)

The potential drawback is that Swihart won’t grow much if he’s not playing every day -- and in particular, if he's not catching every day. But the Sox may be be at a juncture where they feel his bat is a worthwhile experiment off the bench, at least for this season. They can figure out his future -- and their future at backstop -- later.

"He’s a great athlete," Cora told reporters on Sunday. "We’ve seen it in the batter’s box. It’s not only the results, but the way he’s driving the ball to left field as a left-hander, the quality of at-bats as a right-hander. [On Saturday], as a pinch-hitter, that kid was throwing 99 and he throws a breaking ball and squares a ball up."

Swihart entered Monday with a .283 average in Grapefruit League play, with a .905 OPS and a pair of home runs. But he does not have the infield experience that Marrero or Holt has, and the Red Sox essentially have to carry one of those two to start the year.

Eduardo Nunez, the temporary replacement for Dustin Pedroia, is coming off a knee injury, and a sure-handed infielder -- Marrero’s glove is particularly good -- is a must. Rafael Devers is still coming into his own at third base.

Tzu-Wei Lin is available in the minors too, and the Sox could see some redundancy with him, Holt and Marrero. Lin, unlike Marrero, has minor league options remaining. Lin also has some limited outfield experience.

The way the Sox roster looks now, they have two spots available for the three guys: Marrero, Holt and Swihart. Health can change that. Holt, despite being the most veteran of the group, has minor league options remaining, so he theoretically could go to Triple-A to start the season. But if the Sox don't see a role for him on this year's team any way, they'd be wiser trading him, considering he's due to make $2.225 million. It also would be kindest choice for Holt, to let him have an opportunity elsewhere, if one exists.

Swihart has played first base, third base and left field in addition to catching this spring. Perhaps, in time, there will be a way to work Swihart in behind the plate for the Sox. At the least, retaining him would be insurance if Christian Vazquez or Sandy Leon do not perform well offensively.

There was a clear personal-catcher system for the Red Sox in 2017. Leon was Chris Sale’s guy, for example. Manager Alex Cora said he is not taking that approach. As an auxiliary effect, moving away from a personal-catcher system might make it easier for Swihart to receive more time behind the plate, if called on.

"Whoever I feel comfortable with that day behind the plate, he'll catch," Cora told reporters in Florida. "Christian already caught him. Sandy's going to catch him today. And then the next turn, Christian's going to catch him. Everybody's going to work with everybody."
